Compliance Checks Tables 212.3 Activation TableThe following table puts together the essential parameters that are needed for each check to fire. Thefollowing assumptions are made with respect to this table.1. The user of the document and the following tables is aware of the OCP protocol andunderstands that a combination of these parameters can lead to an illegal configuration.2. Every check in the tables below will only talk about the minimum parameters needed for eachcheck to be fired. Each configuration needs the parameters defined for each check in thistable and also every other parameter needed to make it a legal configuration to start with. Forexample, a check for INCR bursts would at the minimum need some command (read_enable,write_enable, etc.) parameters defined to test the check .1.
